1. Introduction: Although plastic is an essential material in our life. It is used in automotive, electronics, buildings and other industries. This production of this material increased in recent years, which has led to a big environmental problem. The plastic waste is not a biodegradable material. Recycling of plastic waste to produce new materials is one of the solution for getting rid of the mountains of trash. A vast work has been done on the use of various plastic waste as aggregates or fillers or fibres in concrete such as height, polytelene terephthalate (pet) [1-4], polystyrene (PS) [5], expanded polystyrene [6], polyvinylchloride (pvc) [7], low density polythene (LDPE) [8], height density polythene (HDPE) [9], E-plastic waste [10], in mortars (pet) [11-13]. The researchers indicated that the waste plastic could be reused as partial substitutes for sand [14], [2, 7, 14] or coarse aggregate [10]. The research revealed that the incorporation of any types or form or size of plastic waste as aggregates generally decreases the dry density [2, 5, 10, 15]. [15] proposed the use of waste plastic with 10, 15, and 20 % plastic aggregates as replacement of fine aggregates in concrete. The results show that the compressive strength and the flexural strength decrease with increasing the waste plastic ratio. [10] studied the utilization of E-plastic waste as fine and coarse aggregate in concrete with percentage replacement ranging from 0%, 10%, 20 and 30%, the study show also that the mechanical properties of concrete contain the E-plastic waste are lower than the concrete without E-plastic waste. The use of plastics waste in the concrete give a good advantage to reducing the unit weight of it. But gives lower compressive strength and tensile strength.[1, 2, 7, 11, 12, 16] A review on the use of the plastic waste in manufacturing of concrete or mortar are available[16] however in this paper based to find a new method to valorized the recycled height density polythene and used a natural source abounds The recycled height density polythene (HDPEr) melted and mixed with the sand dune (SD) to produce new material used as roof tile. An experimental test program is conducted on composite containing different percentages of HDPEr. 2. Experimental program: The experimental program is: Showed that the composite can be made with different percentage. Studied the characteristic of this new material. Compared the results obtained with a clay roof tile flat (without plastic) and with the standard. 2.1. Materials: 2.1.1.

2.2. Mixtures preparation: 2.2.1. Materials needed To facilitate the manufacture the roof tile we used mold size (100 x 100) mm. a mixer, Oven, Machine compression. In this research, a control clay roof tile and six mixes were studied. The compositions of polymer roof tiles are characterized by their proportion in 30, 40, 50, 60, 70, and 80% in weight. The compositions of the six proportions of roof tile presented in the table 3. The polymer roof tiles are fabricated according to the process described below: Weigh the required quantity of sand dune (SD) and HDPEr. Mix and melt the HDPEr with the sand dune (SD) in the Mixer for few minutes. Place the mixture in the oven for 10 minutes than remove it Put the composite in the mold and apply the load using a press. Unmold after cooling the mixture to air.

After the manufacture of the roof tile tow proportion were eliminated: Pro 01 (30% HDPEr of with 70% SD) because haven’t the enough amount of plastic necessary to bond and get a completely tile. Pro 06 (80% of HDPEr with 20% SD) because it are deformed. 3. Results and discussion: 3.1. Density: The test of density was carried out according to NF P 18-554 [22]. The density of a composite polymer roof tile are presented in Fig. 3. The results indicated that the density tends to decrease with the increasing the plastic waste ratio in each roof tile mixture.

3.2. The breaking load by flexural: The test of breaking load by flexural was carried out according to NF EN 538 [23]. The results of the breaking load by flexural tests for the polymer roof tile mixtures pro (0), pro (40), pro (50), pro (60), pro (70) are illustrated in Fig. 4. The results show that the breaking load values of all polymer roof tile mix tend to increase below the values of the roof tile reference and the standard with increasing of amount of HDPEr. This is logical. When the ratio of HDPEr (The binder) increased that gives the material enough bond strength which that led to increase the breaking load.

4. Conclusions In our study we have successfully demonstrated that it is possible to manufactured roof tile from recycled HDPEr and sand dune. This is one of the most effective methods that can be applied to get rid and save the world form the environmental pollutants. However two mixes are suspended because the pro6 (80) gives a very deformable tile and the second pro1 (30) does not have enough resin (binder) so that the mixture adhere. It is noticeable that the density decreases with the increase of the HDPEr ratio that gives the polymer tile to a light weight. And also the polymer roof tile containing 70% HDPEr with 30% sand dune gives the best quality. Further all polymer roof tile mix gives a good results in the permeability coefficient according the standard. As a mechanical result the breaking load of all polymer roof tile mix was lower than the clay roof tile reference as well as the standard. According the results this polymer roof tile has potential to be used as Clay roof tile.
